coLLArsIBLE CAMP BED.

Application filed June 25, 1921. Serial No. 480,278.

ful Collapsible Camp` Bed, of which the following is a specification.

'An object of the invention is to `provide a simple bed which is leasilycollapsible into compactform for storage and transportation.

Another object is to provide for powerful leverage easily applied inthe operation of setting up the bed, ,whereby the bed bottom will be drawn taut andall of the parts including detachable legs will be held together with perfect `rigidity within the requirements ofthe art.

The invention comprises the combination with av spring bed bottom, yof a frame, members of which are hinged together by hinges having the axes of their pivots at right angles to the plane of the bed bottom and arranged on the inner sides of said members so that the members can be bent outward in the operation of collapsing the frame, and forced back from the outwardly bent position to the straight position with practical ease in setting up the frame; and by this, construction it is possible to utilize the spring bed bottom as a purchase to assist inapplying toggle joint leverage to the work of stretching the spring bed bottom, and putting it under tension.

Another feature of the invention is the use 'of the supporting legs to pivot together the rigid and the toggle jointed members of the frame so that when the members which are jointed between their ends are brought into extended position to stretch the bed bottom, the action of the springs of the bed bottom tend to draw opposite members of the frame toward each other to cooperate with the leverage of the jointed frame members so as to `clamp thelegs in place and to give absolute rigidityto they legs as well as to the frame when the frame is stretched.

Another object is to provide a combined metalV and wood collapsiblel frame of great strength and lightness.

Other objects, advantages and features of invention may appear from the accompanying drawing, ythe subjoined detail description and the appended claims.

The accompanying drawing illustrates the invention;

Figure lis a broken plan of an erected camp bed constructed in accordance with this invention. Parts of one of the jointed frame members are shown in horizontal section on line 1-1, Fig. 2.

Fig. 2 is a fragmental elevation in section on irregular line wZ-Z, Fig. l.

Fig. 3 is a reduced plan of the camp bed shown in Fig. l. Dotted lines indicate a position ofk parts during theoperation of bringing the collapsible camp bed to the set-up form.

Fig. 4 is a top view of one of thev side` frame members collapsed.

Fig. 5 is a fragmental view of a lmodified form of the camp bed. i

Fig. 6 is a perspective view of one of the toggle joint hinges.

Fig. 7 is an end view of one of the side members.

Preferably the jointed members are each constructed with two wooden bars of equal length; making four of such bars to eachV bed frame.

lt is understood that any suitable material and any appropriate dimensions may be used in the construction of this invention and thatthe materials therein specified are those that are preferred.

The collapsible rectangular bed frame l consists of the pairs of members comprising end plates 2, 3, and knuckle jointed side members 4, 5, that are pivotally connected atvthe corners of frame l by cylindrical posts or legs 6.

The end plates 2, 3 are provided with flanges 7, 8 between which the ends of jointed members 4, 5 are adapted to fit; and through the flanges 7, 8 are holes 9 that are adapted to register with holes 10 through the ends of jointed members 4, 5; and the legs 6 are made a sliding fit through holes 9, 10 to pivotally connect the frame members together.

Legs 6 are provided with cotter pins or supports 11 at a predetermined height that temporarily hold the bed frame 1 up in a horizontal plane while'the bed is in course of erection. To this end the respective ends of members 2, 3 and 4, 5 are placed together and the top ends of the four legs inserted from the underside of the registering holes 9, l0 until the Cotter pins or stops 11 contact with the bottom flanges 8 of end plates 2, 3 whereby the 'frame is supported until the erection of the bed is comone another as shown by dotted lines in y Fig. 3.

A flexible bed bottom 14 is attached to end plates 2, 3 and is adapted to be collapsed into a bundle between these vends when the bed is dismounted. The bottom 14 preferably is wire Jfabric 'tliathasits ends to flangeslof ends- 2, 3. y n

Parts' 1.2,' l13 are connected vby hinge members'16,17 with bearing` pins 18 that are secured byrive'ts'lf) to their 'respectiveparts- The hinge members "16 have elongated flanges 20 thatV are "connected by a weband adapted tovpartly enclosethe hinged ends of parts "13 when they are in lalinernent with parts 12;V andthe `flanges 2,0 have holes adapted to register V with similar 'holes in the hinged ends of 13 and to receive cotter pins 21 that when in place holdparts 12 and`1'3 in alineme'ntr in 'extended' position and the web ,portion 22 of extension 2O are stops that prevent the pairs of jointed members 4, 5 yfrom being'moved inward farther than to a fully extended position.

When the bed is to be "erected, the bottom` 14 is unrolledandends 2, 3 spread apart much as can be done by hand. Then lthe jointed membe'r4, 5 are 'placed Ain `position as` herei'nbeffore ,described an'dlegs G inserted in place, which will position the frame 1 asshown by dotted lines in Fig. 3. yThen pressiirefis applied to the joints of members 4, 5 to 'move `themfrom:the dotted to the full line v,positionshown in Fig. 3 which stretclies'the Abed bottom' 14 and applies Ac onsiderable tension'to spring 15. Also this toggle movement of theointedmembers 4, 5 causes clasping or binding pressure 'to be appliedito the bedleg's'G in a direction opposite'kto'the pull-applied by springsv 15 on the e'nds2, 3 so that the legs 6 are firmly clamped between the flanges of' ends 2, 3 andV the endsof'the jointed emeinbe'rsry4, 5; `and this clamping oflegj's '6 is so great that the full weight ofthe bed rand occupants is supprtedfindepenlently of the cotter pins'll.

The bed Ican be construeted ofanymaterial andufinished as "desired Preferably I construct I,my v end,v ypl'ates of angle, irons to which short angle plates are secured'to form the lower flanges 8 thatparallel flanges 7.

The jointed' side members'4, 5 are preferably formed of woodenparts-12, 13 that have sockets 23`riveted to their ends, so `Athat the legs 6 vare `7pinched between Vmetallic surfaceswhen thebed is assembled.

A modified form ol constructing and connectingthe framemembers 2, 3 and '4, 5 is shown in Fig. 5. The ends ofthe side members'are slotted at 24 to receive/'the flanges 7 of'end members 2,3. The pivotal connection and pressure applied tohold the pivot the jointed members is in place issubstantially the same as herein- 'bef'ore described.

The parts are collapsed and disconnected by removinov the Cotter pins 21 and then movi`ng""theii!`4 edi'lsde members 4, 5 from 4a fully extende position indicated by full lines "in Fig. to the dotted line or collapsed position .shown therein; which re- "moves :tension frointhe bed bottom 14 and provided with springs 15tbat are connected releases the pinching or clasping ipressure on legs 6 so that they can be removed to separate the ends of the-end and-side members 2, a, 4, 5. l I y y lThen the hingedF side members are-folded as shown-inFig. 4 after which the bedj bottom 14 is 'foldedbetweenend members 2, 3. Then the parts can ell'beassembled into a single compact bundle.

The invention-lisl broadly new, basic and vpioneer in that the ufraineis constructed with Fjointedwrails or side members which bend outwardly sidewisei relative 1 to the frame in the collapsingy 'operation' andere jpus'hed in sidewise in Vtheroperationofsetting up the bed; and the top andbotbom of erich` n encased at one end by the hinge memberw'hicli i'sfi'xe'd to one of said bars. In this Way `I make itpossible for the person setting up the"`bed to utilize the partially stretched bed bottom asapurehase to enable him to -e'asily'opeiate the 'toggle joint yfor giving Atension Ato 4the' spring bed bottom, but Ik also `seere great f-rigidityof frame and hold thejoiited members rigidly;

and the bed can only be'eollapsed,by the application of considerable force sidewise to 'spread Ythe "knuckle Afjoints-lapart. `The amount of such Aforce willdepend pon the ytension placed upon fthe springs.

In setting up the 4bed having-tlie' sprin bed bottom 'fixed tofthemeinbes 2, 3, en the legs inserted asl shown 3i`n`Fig. 2.5 lthe loperator will frstbring'one ofthe hside inembers into the straight position. -This isveasily done because l`the end 'members 2, bei

when erecting the-y bed.

An advantage'of havingthelve'l '6 detachably connecting the sideede'n frames f the bed is that azfveryfempaet bundle" is obtained whenl thebed is in collapsed position. Y

A further 'adv'entgftfltf having the A1 6 detachably and pivtlly 4eoiieeting't e bar ofy ibs i v I I ng' 110 oblique to the sidey Imember"that'ha'sbeen `'straiglitened, leave the bed-'bottfri free 'from to the end pair of said frame members; de-

tachable legs forming a pivotal connection between the. ends of the pairs of end and side frame members; and'hinges interposed in the pair of side frame members; said hinges being arranged to extend said side members and clamp the legs in place when the end and side fra-me members are pivotally connected and when said hinges are moved toward one another.

2. In a collapsible bed having a pair of side and a pair of end frame members and a sprin bed bottom with opposite ends connecte to said pair of end frame members, legs detachably and pivotally connectingthe ends of said pairs of end and side frame members, hinges interposed in said side `frame members and arranged to extend said side frame members to apply tension to said spring bed bottom and pressure on said legs to hold them in pla-ce when the hinged portions of said end are moved toward one another, means for limiting the movement of said hinges toward one another when the ends of said end and side frame members are pivotally connected, and means for holding said side frame members in extended position when said hinges have reached the limit of movement toward one another.

3. In a collapsible bed having a pair of side and a pair of end frame members and a spring bed bottom with op osite ends connected to said pair of end rame members, legs detachably connecting the ends of the end and side frame members; said legs forming pivots between said side and end frame members; hinges interposed in said side members and arranged so that said side members have a toggle movement relative to the end frame members to extend said side frame members and apply tension to the spring bed bottom and to clasp or pinch the leg pivots; webbed stops connected with said hinges to limit their movement in one direction, and means for holding said side frame members in extended position when they have been moved to apply tension to the spring bed bottom and pinch or clasp said legs.

4. In combination with a spring bed bottom, two frame members fastened to the Spring bed bottom; two toggle jointed members pivoted to the rst named members by legs projecting from one side of said frame so that the tension put upon the spring bed bottom by extending the jointed members will clamp the legs in place.

5. In a collapsible bed having a pair of end frame members and a spring bed bottom with opposite ends connected to said members; a pair of side frame members; legs detachably and pivotally connecting the ends of said pair of side frame members to the ends of said pair of end frame members and provided with stops to support said pairs oi members; and hinges interposed in said pair of side frame members and arranged to extend said side frame members to apply tension to said spring bed bottom and Ito clamp said legs in position.
